# AlarmClock

`public final class AlarmClock`
`extends Object` ``

java.lang.Object
↳ | android.provider.AlarmClock

The AlarmClock provider contains an Intent action and extras that can be used to start an Activity to set a new alarm or timer in an alarm clock application. Applications that wish to receive the ACTION_SET_ALARM and ACTION_SET_TIMER Intents should create an activity to handle the Intent that requires the permission com.android.alarm.permission.SET_ALARM. Applications that wish to create a new alarm or timer should use `Context.startActivity()` so that the user has the option of choosing which alarm clock application to use. Android TV devices may not support the alarm intents.

## Constants

### ACTION_DISMISS_ALARM

    public static final String ACTION_DISMISS_ALARM

Activity Action: Dismiss an alarm.

The alarm to dismiss can be specified or searched for in one of the following ways:

1. The Intent's data URI, which represents a deeplink to the alarm.
2. The extra `EXTRA_ALARM_SEARCH_MODE` to determine how to search for the alarm.

If neither of the above are given then:

- If exactly one active alarm exists, it is dismissed.
- If more than one active alarm exists, the user is prompted to choose the alarm to dismiss.

If the extra `EXTRA_ALARM_SEARCH_MODE` is used, and the search results contain two or more matching alarms, then the implementation should show an UI with the results and allow the user to select the alarm to dismiss. If the implementation supports `Intent.CATEGORY_VOICE` and the activity is started in Voice Interaction mode (i.e. check `Activity.isVoiceInteraction()`), then the implementation should additionally use `VoiceInteractor.PickOptionRequest` to start a voice interaction follow-on flow to help the user disambiguate the alarm by voice.

If the specified alarm is a single occurrence alarm, then dismissing it effectively disables the alarm; it will never ring again unless explicitly re-enabled.

If the specified alarm is a repeating alarm, then dismissing it only prevents the upcoming instance from ringing. The alarm remains enabled so that it will still ring on the date and time of the next instance (i.e. the instance after the upcoming one).

See also:

- `EXTRA_ALARM_SEARCH_MODE`

Constant Value: "android.intent.action.DISMISS_ALARM"

### ACTION_DISMISS_TIMER

    public static final String ACTION_DISMISS_TIMER

Activity Action: Dismiss a timer.

The timer to dismiss should be specified using the Intent's data URI, which represents a deeplink to the timer.

If no data URI is provided, dismiss all expired timers.

Constant Value: "android.intent.action.DISMISS_TIMER"

### ACTION_SET_ALARM

    public static final String ACTION_SET_ALARM

Activity Action: Set an alarm.

Activates an existing alarm or creates a new one.

This action requests an alarm to be set for a given time of day. If no time of day is specified, an implementation should start an activity that is capable of setting an alarm (`EXTRA_SKIP_UI` is ignored in this case). If a time of day is specified, and `EXTRA_SKIP_UI` is `true`, and the alarm is not repeating, the implementation should remove this alarm after it has been dismissed. If an identical alarm exists matching all parameters, the implementation may re-use it instead of creating a new one (in this case, the alarm should not be removed after dismissal).

This action always enables the alarm.

This activity could also be started in Voice Interaction mode. The activity should check `Activity.isVoiceInteraction()`, and if true, the implementation should report a deeplink of the created/enabled alarm using `VoiceInteractor.CompleteVoiceRequest`. This allows follow-on voice actions such as `ACTION_DISMISS_ALARM` to dismiss the alarm that was just enabled.

### Request parameters

- `EXTRA_HOUR` (optional): The hour of the alarm being set.
- `EXTRA_MINUTES` (optional): The minutes of the alarm being set.
- `EXTRA_DAYS` (optional): Weekdays for repeating alarm.
- `EXTRA_MESSAGE` (optional): A custom message for the alarm.
- `EXTRA_RINGTONE` (optional): A ringtone to play with this alarm.
- `EXTRA_VIBRATE` (optional): Whether or not to activate the device vibrator for this alarm.
- `EXTRA_SKIP_UI` (optional): Whether or not to display an activity for setting this alarm.

Constant Value: "android.intent.action.SET_ALARM"

### ACTION_SET_TIMER

    public static final String ACTION_SET_TIMER

Activity Action: Set a timer.

Activates an existing timer or creates a new one.

This action requests a timer to be started for a specific `length` of time. If no `length` is specified, the implementation should start an activity that is capable of setting a timer (`EXTRA_SKIP_UI` is ignored in this case). If a `length` is specified, and `EXTRA_SKIP_UI` is `true`, the implementation should remove this timer after it has been dismissed. If an identical, unused timer exists matching both parameters, an implementation may re-use it instead of creating a new one (in this case, the timer should not be removed after dismissal). This action always starts the timer.

### Request parameters

- `EXTRA_LENGTH` (optional): The length of the timer being set.
- `EXTRA_MESSAGE` (optional): A custom message for the timer.
- `EXTRA_SKIP_UI` (optional): Whether or not to display an activity for setting this timer.

Constant Value: "android.intent.action.SET_TIMER"

### ACTION_SHOW_ALARMS

    public static final String ACTION_SHOW_ALARMS

Activity Action: Show the alarms.

This action opens the alarms page.

Constant Value: "android.intent.action.SHOW_ALARMS"

### ACTION_SHOW_TIMERS

    public static final String ACTION_SHOW_TIMERS

Activity Action: Show the timers.

This action opens the timers page.

Constant Value: "android.intent.action.SHOW_TIMERS"

### ACTION_SNOOZE_ALARM

    public static final String ACTION_SNOOZE_ALARM

Activity Action: Snooze a currently ringing alarm.

Snoozes the currently ringing alarm. The extra `EXTRA_ALARM_SNOOZE_DURATION` can be optionally set to specify the snooze duration; if unset, the implementation should use a reasonable default, for example 10 minutes. The alarm should ring again after the snooze duration.

Note: setting the extra `EXTRA_ALARM_SNOOZE_DURATION` does not change the default snooze duration; it's only applied to the currently ringing alarm.

If there is no currently ringing alarm, then this is a no-op.

See also:

- `EXTRA_ALARM_SNOOZE_DURATION`

Constant Value: "android.intent.action.SNOOZE_ALARM"

### ALARM_SEARCH_MODE_TIME

    public static final String ALARM_SEARCH_MODE_TIME

- `EXTRA_MINUTES` - The minute to search for the alarm.
- `EXTRA_IS_PM` - Whether the hour is AM or PM.

See also:

- `EXTRA_ALARM_SEARCH_MODE`

Constant Value: "android.time"

### EXTRA_ALARM_SEARCH_MODE

    public static final String EXTRA_ALARM_SEARCH_MODE

### EXTRA_ALARM_SNOOZE_DURATION

    public static final String EXTRA_ALARM_SNOOZE_DURATION

Bundle extra: The snooze duration of the alarm in minutes.

Used by `ACTION_SNOOZE_ALARM`. This extra is optional and the value is an `Integer` that specifies the duration in minutes for which to snooze the alarm.

See also:

Constant Value: "android.intent.extra.alarm.SNOOZE_DURATION"

### EXTRA_DAYS

- `Calendar.THURSDAY`,
- `Calendar.FRIDAY`,

Constant Value: "android.intent.extra.alarm.DAYS"

### EXTRA_HOUR

    public static final String EXTRA_HOUR

Bundle extra: The hour of the alarm.

Used by `ACTION_SET_ALARM`.

This extra is optional. If not provided, an implementation should open an activity that allows a user to set an alarm with user provided time.

The implementation should look up the alarm that is most closely matched by these search parameters. If `EXTRA_IS_PM` is missing, then the AM/PM of the specified `EXTRA_HOUR` is ambiguous and the implementation should ask for clarification from the user.

The value is a `Boolean`, where false=AM and true=PM.
